By using appropriate material property values, the experimental results and analysis results are almost consistent!
To improve the analysis accuracy of rubber, it is important to define appropriate material properties. Since there are limitations to the material properties obtained from uniaxial tensile tests, biaxial tensile tests, which provide suitable material properties for rubber CAE analysis, are effective. In the case of rubber CAE analysis, it is evident that the strain distribution from the biaxial test (pure shear) is closer to the actual measurements than that from the uniaxial test. In other words, to enhance the accuracy of CAE analysis, it is recommended to use the material properties obtained from biaxial tests (pure shear).

basic information
This testing machine is a device for obtaining the material properties of rubber, equipped with a jig for biaxial tensile testing on a commercially available small testing machine. This testing machine is a portable, compact tabletop device that can be easily carried and allows for biaxial tensile testing with a disk work feel. We pursued improved workability and operability on-site, ensuring minimal button operations, easy-to-read displays, and ample workspace. By adopting a two-column structure, it enables stable testing with high precision and reliability, free from the misalignment or tilt of the testing axis that can occur with a single-column design.

Applications/Examples of results
A biaxial static tensile test can be conducted. Based on the results of the biaxial test, material constants necessary for CAE analysis (such as Mooney and Ogden) can be obtained. Uniaxially constrained biaxial tensile test - Target material: Rubber - Output items: Load - Displacement - Material constants: Mooney, Ogden

Company information
In recent years, as the globalization and complexity of manufacturing have progressed, it has become increasingly difficult for companies to strengthen their own manufacturing independently and maintain a competitive edge over others. Looking overseas, companies and public institutions are actively collaborating to strengthen their own manufacturing capabilities, taking into account the trends of globalization. To ensure that Japan continues to strengthen its manufacturing capabilities in the future, it is essential for companies, universities, and public institutions to collaborate and enhance their co-creation awareness. Therefore, our company provides the best "manufacturing support services" for our customers based on the philosophy of "supporting manufacturing through collaboration with industry, academia, and government." ■ Mission We provide the best "manufacturing support services" for our customers. ■ Vision To ensure that Japan remains one of the world's leading manufacturing nations, we aim to promote organic collaboration with industry, academia, and government, and create a system where Japanese engineers can enjoy advanced skills and technologies.
